Procuring industrial grade Polyaluminum Chloride (PAC) requires a disciplined approach that balances technical performance with regulatory compliance and supply chain reliability. As a high-efficiency inorganic coagulant, PAC is widely utilized in water treatment and sewage management. The market presents a complex landscape where product attributes vary significantly between batches and suppliers. Buyers must navigate a range of specifications, from basicity levels and aluminum oxide content to packaging standards and certification requirements. This guide provides a structured framework for evaluating suppliers and products based on verified industry data and observed market parameters, ensuring that procurement decisions are grounded in factual evidence rather than unverified claims.

Technical Specifications and Chemical Properties

The fundamental utility of Polyaluminum Chloride lies in its chemical composition and physical state. Based on observed market data, the product typically appears as a powder or solid, with color variations ranging from yellow to white. The chemical name is consistently identified as Polyaluminum Chloride, often associated with the CAS number 1327-41-9. However, buyers must exercise caution when interpreting these identifiers, as they represent common industry markers rather than universal guarantees for every listed unit.

A critical parameter for performance is the Basicity, which dictates the coagulation efficiency and the resulting sludge volume. Observed data indicates a wide range of basicity levels, specifically noted between 30% and 95%. This variance suggests that different models, such as PAC-031 or zq-001, are engineered for distinct operational environments. Similarly, the Aluminum Oxide (Al2O3) content is a primary indicator of potency. Market observations list this content in several ranges, including 27% to 28%, a specific 28% value, and broader bands like 28% to 31% or 26% to 31%. When sourcing, the buyer must verify the specific Al2O3 percentage required for their application, as lower content may necessitate higher dosages, affecting overall operational costs.

The pH level of the product solution is another vital technical specification. Data points suggest a pH range of 3.5 to 5.0, classifying the substance as an acidic surface disposal agent. This acidity is essential for its function in neutralizing alkaline impurities in water. Additionally, the purity of the product is a key differentiator. While some entries list purity between 30% and 50%, others claim a purity of ≥99%. These discrepancies highlight the necessity of requesting specific batch analysis reports rather than relying on general product descriptions. The grade standard is uniformly identified as Industrial Grade, confirming its suitability for large-scale municipal and industrial applications rather than specialized laboratory use.

Compliance, Certification, and Regulatory Standards

Navigating the regulatory landscape is paramount for industrial buyers, particularly when sourcing chemicals for environmental applications. The supply chain for Polyaluminum Chloride involves multiple layers of compliance, including international standards, national technical requirements, and specific environmental certifications. Observed data confirms the existence of several certification types, including ISO, RoHS, CE, REACH, and WQA. The presence of these certifications is a strong indicator of a supplier's commitment to quality management and environmental safety, but they must be verified against the specific product batch.

Technical compliance is often anchored in national standards. One specific standard observed is GB15892-2003, which serves as a benchmark for the technical requirements of Polyaluminum Chloride in certain markets. Buyers should treat this as a reference point for verifying that the product meets established quality thresholds. Furthermore, the product standard itself varies, with some listings citing "International" standards, while others specify "Water Treatment" as the standard category. This variation underscores the need for buyers to explicitly request the applicable standard document for the specific model they intend to purchase.

Environmental protection is a core attribute of the product, with data confirming that the chemical is designed with environmental considerations in mind. However, the specific certifications held by a supplier, such as ISO or REACH, are not automatically transferable to every product listing. A supplier may hold an ISO certificate for their facility, but a specific batch of PAC must still undergo testing to ensure it meets the required purity and heavy metal limits. Therefore, buyers should demand valid, up-to-date certificates of analysis (COA) that align with the claimed certifications. The presence of a "bluwat" standard in some listings suggests proprietary or specific industry classifications that require clarification during the supplier evaluation phase.

Cost Drivers and Pricing Dynamics

Understanding the cost structure of industrial grade Polyaluminum Chloride is essential for budgeting and total cost of ownership analysis. The observed price range in the market is extensive, spanning from $0.46 to $500 per unit. This wide disparity is not indicative of a single product type but rather reflects differences in concentration, packaging, purity, and order volume. The minimum order quantity (MOQ) also plays a significant role in pricing, with observed ranges from 1 to 27 units. Lower MOQs often correlate with higher per-unit costs, while bulk purchasing typically drives the price down toward the lower end of the spectrum.

Packaging is a major cost driver that influences both the unit price and logistics expenses. The market offers various packaging options, including 25kg PP woven bags, wooden crates, polyethylene plastic woven packaging, and jumbo bags. Some suppliers offer flexible packaging solutions, such as 25kg/1000kg or custom requirements, which can impact the final cost. The choice of packaging must align with the buyer's storage capabilities and transportation methods. For instance, wooden packaging may incur higher costs and customs duties compared to standard woven bags, but it offers superior protection for long-distance shipping.

The chemical concentration, specifically the Al2O3 content and Basicity, directly affects the price. Products with higher purity (e.g., ≥99%) or higher Al2O3 content (e.g., 28%-31%) generally command a premium over those with lower concentrations. Additionally, customization availability is a factor; products that can be tailored to specific pH or basicity requirements may carry a higher price tag due to the additional processing involved. Buyers should calculate the cost per unit of active ingredient rather than the cost per bag to make accurate comparisons between different suppliers and product grades.

Typical Applications and Performance Context

Industrial grade Polyaluminum Chloride is primarily deployed in water treatment and sewage management scenarios. The product is classified under the type "Sewage Treatment Chemicals" and "Industrial Circulating Water Treatment Agent," indicating its versatility across different sectors. Its application as a coagulant helps in the removal of suspended solids, turbidity, and heavy metals from water sources. The acidic nature of the product makes it particularly effective in adjusting the pH of water while simultaneously flocculating impurities.

The specific application depends heavily on the product's basicity and Al2O3 content. High-basicity PAC is often preferred for treating water with low alkalinity, as it provides better buffering capacity. Conversely, lower basicity products might be more suitable for applications where pH adjustment is the primary goal. The color of the product, whether yellow or white, can sometimes indicate the presence of impurities or the specific manufacturing process used, though this is not a definitive performance metric. Buyers should match the product model, such as YR-017 or Poly Aluminium Chloride, to their specific water treatment needs.

In industrial circulating water systems, PAC is used to control scaling and corrosion. The ability of the chemical to form stable flocs ensures efficient sedimentation, reducing the load on downstream filtration systems.
